Section 13: Health and Safety Information

This section outlines the safety precautions
associated with using your phone. The terms "mobile
device" or "cell phone" are used in this section to
refer to your phone. Read this information before
using your mobile device.
Exposure to Radio Frequency (RF)
Signals
The U.S. Food and Drug Administration (FDA) has
published information for consumers relating to
Radio Frequency (RF) exposure from wireless phones.
The FDA publication includes the following
information:
Do cell phones pose a health hazard?
Many people are concerned that cell phone radiation
will cause cancer or other serious health hazards.
The weight of scientific evidence has not linked cell
phones with any health problems.
Cell phones emit low levels of Radio Frequency (RF)
energy. Over the past 15 years, scientists have
conducted hundreds of studies looking at the
biological effects of the radio frequency energy
emitted by cell phones. While some researchers have
reported biological changes associated with RF
energy, these studies have failed to be replicated.
The majority of studies published have failed to show
an association between exposure to radio frequency
from a cell phone and health problems.
The low levels of RF cell phones emit while in use are
in the microwave frequency range. They also emit RF
at substantially reduced time intervals when in the
stand-by mode. Whereas high levels of RF can
produce health effects (by heating tissue), exposure
to low level RF that does not produce heating effects
causes no known adverse health effects.
The biological effects of radio frequency energy
should not be confused with the effects from other
types of electromagnetic energy.
Very high levels of electromagnetic energy, such as is
found in X-rays and gamma rays, can ionize
biological tissues. Ionization is a process where
electrons are stripped away from their normal
locations in atoms and molecules. It can permanently
damage biological tissues including DNA, the genetic
material.
The energy levels associated with radio frequency
energy, including both radio waves and microwaves,
are not great enough to cause ionization of atoms
and molecules. Therefore, RF energy is a type of non-
ionizing radiation. Other types of non-ionizing
radiation include visible light, infrared radiation
(heat), and other forms of electromagnetic radiation
with relatively low frequencies.
While RF energy does not ionize particles, large
amounts can increase body temperatures and cause
tissue damage. Two areas of the body, the eyes and
the testes, are particularly vulnerable to RF heating
because there is relatively little blood flow in them to
carry away excess heat.
